Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery pole piece production, and in particular to a grid casting machine. Background Art

[0002] Lead-acid batteries are composed of positive and negative plates, separators and electrolytes, battery tanks and connecting strips (or lead parts), terminals and exhaust valves, etc. The positive and negative plates are also called grids, which are cast from lead-based alloys. A lead-acid battery requires a large number of positive and negative plates, and battery factories need to produce plates at a high speed.

[0003] The existing problems of cast grid machines are: 1. The distribution of lead melting furnaces is relatively scattered. The large amount of lead fume gas volatilized by the lead melting furnaces during operation can easily spread to the entire workshop space, which is not conducive to the collection and treatment of lead fume gas in the workshop by environmental protection equipment, and causes great pollution to the health and environment of workshop workers; 2. Multiple lead melting furnaces increase the maintenance burden of workshop maintenance personnel and also increase electricity consumption; 3. When pouring liquid lead-based alloy onto the mold, the flow rate of the liquid lead-based alloy cannot be controlled, resulting in excessive casting and failure to achieve the casting state desired by the operator; 4. After the cast grid machine completes the production of the pole pieces, they need to be stacked manually, which increases labor intensity and reduces production efficiency.
